       mbsinit - test for initial shift state

       #include <wchar.h>

       int mbsinit(const mbstate_t *ps);

       Character  conversion between the multibyte representation and the wide
       character representation uses  conversion  state,  of  type  mbstate_t.
       Conversion  of  a string uses a finite-state machine; when it is inter‐
       rupted after the complete conversion of a number of characters, it  may
       need  to	 save a state for processing the remaining characters.	Such a
       conversion state is needed for the sake of encodings such  as  ISO-2022
       and UTF-7.

       The  initial  state  is	the  state at the beginning of conversion of a
       string.	There are two kinds of state: The one  used  by	 multibyte  to
       wide  character conversion functions, such as mbsrtowcs(3), and the one
       used by wide character to multibyte conversion functions, such as wcsr‐
       tombs(3), but they both fit in a mbstate_t, and they both have the same
       representation for an initial state.

       For 8-bit encodings, all states are equivalent to  the  initial	state.
       For multibyte encodings like UTF-8, EUC-*, BIG5 or SJIS, the wide char‐
       acter to	 multibyte  conversion	functions  never  produce  non-initial
       states,	but  the multibyte to wide-character conversion functions like
       mbrtowc(3) do produce non-initial states when interrupted in the middle
       of a character.

       One  possible  way to create an mbstate_t in initial state is to set it
       to zero:

	   mbstate_t state;

       On Linux, the following works as	 well,	but  might  generate  compiler

	   mbstate_t state = { 0 };

       The  function  mbsinit()	 tests	whether	 *ps corresponds to an initial

       mbsinit() returns nonzero if *ps is an initial state, or if ps is NULL.
       Otherwise it returns 0.

   Multithreading (see pthreads(7))
       The mbsinit() function is thread-safe.


       The  behavior of mbsinit() depends on the LC_CTYPE category of the cur‐
       rent locale.
